"This isn't the BMW website you are looking for"

The zany marketing guys at BMW have come up with (well, stolen) a cunning ruse to get us talking about what looks like a 6 Series concept – telling us not to talk about it... But like a child told not to touch wet paint, we have risen to the bait.

A website called dontblogaboutthis.com has appeared over the last few days with a series of pictures and videos of a mysterious 6 Series prototype. But captions that say: "this is more than a 6 Series" and "nothing is what it seems" suggest that there is something a little different about this car.
